Reduce GHG emissions to 80% of 1990 levels
by 2050 * http://www.city-data.com/city/California.html (CARB)
Monitors and enforces reporting, verification and compliance with AB32 Position economy to benefit CA to become a leader in GHG reductions Global warming is a threat California Global Warming Solutions Act – AB32 * California Air Resources Board Long-Term Emission Targets Further reductions through 2050 Deadline for achieving 1990 emission levels Low-Carbon Fuel Standard

GHG Reducing
Activities CARB's scoping plan outlines GHG reducing measures to be implemented

AB 32 will require WWTPs to upgrade systems to reduce stack emissions

It provides mechanisms to help fund these upgrades

Upgrades to wastewater treatment systems can generate $
- the sooner uprades ar implemented
the more $ can be made off of them AB 32: Opportunities for wastewater Annual

Issues Climate Reserve Tonnes (CRTs)
Verifies GHG reductions and issues CRTs Determines which protocols generate CRT’s that are eligible to cover GHG reductions The planting and maintenance of trees in urban areas can reduce greenhouse gasses and earn carbon offsets:
Credits issued based annual on net tree gain
Credits can be sold to other entities
Municipalities, educational campuses and utilities are eligible
Project must be on less than 100 acres
Trees must be a minimum of 5 meters apart
Credits can be accrued for 100 years *Building: Best Clipart Blog *Tree: Smucker Company *Wind: classroomclipart.com * Leaves: polyvore.com *GHG molecules: Spark UCAR Science Education *Sun: Clipart Mountain Trees remove Co2 and other GHG from the atmosphere and sequester them in their leaves, branches trunks and roots. Urban Forest Protocol Trees reduce energy use by blocking out sun and wind, decreasing the need for heating and cooling.
